Why was the nano that was installed manually not colored?

Solution 1:

I believe nano is B/W by default. You can set the colors in /etc/nanorc, like this:

## Paint the interface elements of nano.
## These are examples; by default there are no colors.
set titlecolor black,green
set statuscolor black,yellow
# set selectedcolor brightwhite,magenta
set numbercolor yellow
set keycolor cyan
set functioncolor white

However, syntax highlighting should be colored by default. This thread has information about syntax highlighting in nano - check if the directory /usr/share/nano/ is in fact included in your nanorc file:

include /usr/share/nano/*.nanorc

In addition, for the syntax highlighting to take effect, the file must either have the correct extension, or the correct shebang (#!) in the beginning.
